    Steam turbine ducted fan racing aircraft

    That's correct when steam engine or turbine is rotating propeller and the cooling is done by steam radiators in wings or in fuselage. To solve this problem it was proposed to use much higher pressure and temperature of steam condensation to heat up the jet exhaust of the ducted fan. It works...

    Steam turbine ducted fan racing aircraft

    Besler's steam airplane was able to fly, but its steam condenser cooling capacity wasn't sufficient enough. Estimated top speed was about 125 mph. That was done with 1933 technology and materials.

    Steam turbine ducted fan racing aircraft

    There is no doubt that modern aircraft engines have much better performance than any closed cycle propulsion system. I always thought that steam aircraft is impossible due to very difficult problem of steam condensation. All attempts, except Besler's airplane, were unsuccessful. Yet...

    Steam turbine ducted fan racing aircraft

    Reno air racing is a great show: https://youtu.be/r00SaRYm3Rc Planes fly eight laps, total 64 miles. That's a very short distance. Any project like this will cost a lot. Electric airplanes have very small energy storage and can fly for a very short time, yet there is a great interest in...

    Steam turbine ducted fan racing aircraft

    Steam cycle can use any source of heat including fission energy. But the question was only about technical feasibility of short range high speed steam compressor jet aircraft with the water boiler heated by jet fuel combustion. Reno air racers carry a limited amout of fuel - 100-300 gallons...

    Steam turbine ducted fan racing aircraft

    In 1950s there were several attempts to design steam turbine jet aircrafts: https://digital.library.unt.edu/ark:/67531/metadc58164/m2/1/high_res_d/19930085809.pdf https://digital.library.unt.edu/ark:/67531/metadc52887/m2/1/high_res_d/19630003317.pdf http://hdl.handle.net/2060/19690030675 Here...
